摘要： PROBLEM TO BE SOLVED: To provide a power supply state change over device keeping a situation in which a power supply state is hardly left under a power supply-on state.
SOLUTION: A vehicle provided with a one-push engine start system is provided with a push momentary type engine switch 22 as a power supply state change over operation system. Positions of a switch knob 23 of the engine switch 22 can be changed to a pop up position jumping out from a normal position by a prescribed quantity. When the power supply state (power supply position) of a vehicle is set to the power supply-on state (ACC-on state, IG-on state, and engine start state), the switch knob 23 of the engine switch 22 is popped up by a prescribed quantity to inform a user that the power supply state is the power supply-on state.

摘要： PROBLEM TO BE SOLVED: To readily recovers a relay drive circuit to an output operation state after a short circuit is cancelled while preventing the relay drive circuit from being damaged by the short circuit. SOLUTION: In the short circuit protection circuit, an ECU 1 has the relay drive circuit 11 which outputs a drive current to a relay 2 in accordance with an input relay drive signal A, and a short circuit detection circuit 12. The short circuit detection circuit detects the occurrence of the short circuit at an output side of the relay drive circuit 11 and suspends output operation of the relay drive circuit 11 when the short circuit occurs. Further, the short circuit detection circuit intermittently transmits a recovery signal to the relay drive circuit 11 in a certain time interval after a predetermined time elapses from when the short circuit occurs to recover the output operation of the relay drive circuit. The time interval is gradually increased as time passes, so that the time ratio of the time between a time when the short circuit is resolved, and a time when the output operation of the relay drive circuit 11 is restored, becomes ≤10%, for the time when the short circuit occurred.

摘要： PROBLEM TO BE SOLVED: To reduce the dark current after ignition-off without bringing about a functional drop in monitoring the condition of an in-vehicle switch. SOLUTION: A car-mounted power supply system is structured so that power is supplied from a car-mounted battery by turning on a transistor and the conditional monitoring of the in-vehicle switch by a microcomputer of a load ECU is made possible, whereby the conditional monitoring is executed normally at all times. Discrimination is made whether any person exists in the cabin (Step 200), and also the On-Off state of an ignition switch is discriminated. In a case no person exists in the cabin during execution of the conditional monitoring of the in-vehicle switch in the ignition-off state, power supplying from the battery is prohibited by turning off the transistor so as to interrupt the conditional monitoring of the in-vehicle switch (Step 106).

摘要： PROBLEM TO BE SOLVED: To provide a power source controller capable of efficiently supplying power according to whether towing is performed or not. SOLUTION: The power source controller 3 is mounted to a vehicle 1. The power source controller 3 is equipped with a detection part 5 and a power control part 6. The detection part 5 detects that a trailer 10 connected to the vehicle 1 is in such a state that the power source can be supplied. When the detection part 5 detects that it is in the state where power source can be supplied, the power control part 6 limits the supply of power source electric power for the device (loads 8a-8c at the vehicle side) mounted to the vehicle 1 compared to the case when not being detected.
